A study by Indiana University researchers shows that excess emissions—which occur with plant shut-downs, start-ups, and malfunctions—can make serious contributions to overall air pollution

A naturally occurring protein can break down chlorite, an industrial pollutant found in groundwater, drinking water, and soils, into harmless byproducts

Researchers call for the need to consider low dose and mixture toxicity testing in risk assessment of chemicals entering our aquatic environments

Research team focused on copper-exchanged zeolites, a particular class of catalysts used to promote the conversion of NO_x into environmentally benign nitrogen gas

Bacteria provide a microbial partner to help protect trees from the toxic effects of pollutants and break down the toxins plants bring in from contaminated groundwater

Rice University research shows reusable, carbon nanotube-reinforced filters clean toxins from water

Material adsorbs more than 90 percent of the dye and enhances the rate of dye breakdown by almost ten times using visible light

Novel material removes pollutant PFOA to levels far below EPA’s health advisory limit

Constant stuffy, drippy nose may not be from allergies

Results will guide design of improved catalysts for transforming pollutant to useful chemicals
